Mil-Spec Fire Control Group

The kit includes a full mil-spec fire control group. That covers the standard curved mil-spec trigger, the hammer, and the disconnector, along with the trigger pin and hammer pin. The trigger, hammer, and disconnector springs are also included. These parts make up the core trigger group of the AR-15 lower.

Controls and Trigger Guard

The kit includes the main lower controls, starting with the safety selector and its detent. It also includes the magazine catch, magazine release button, and bolt catch with its bolt catch buffer and roll pin. The trigger guard and trigger guard roll pin round out the exterior parts. Together, these pieces cover the controls and small hardware found on a standard AR-15 lower.

Pins, Detents, and Springs

The pivot pin and takedown pin are included along with their detents. The buffer retainer is also part of the kit. Springs are included for the trigger, hammer, magazine catch, buffer retainer, safety selector, bolt catch, disconnector, pivot pin detent, and takedown pin detent. That full spring set means the small parts are all covered in one kit.

Pistol Grip Hardware Without Grip

This kit does not include a pistol grip. The grip screw and washer are included. That leaves the choice of pistol grip open to the buyer. It suits builders who already have a grip in mind or want to pick one separately.
